COTTON-SEED HULLING AND REDUCING MACHINE.

SPECIFICATION forming part of Letters Patent No. 678,088, dated July 9, 1901.

7 Application filed March 20, 1900. Serial No. 9,448. (No model.)

.To whom it may concerns .Be it known that I, CORNELIUS YOUNG, a citizen of the United States, and a resident of Selma, in the county of Dallas and State of Alabama, have made a certain new and useful Invention in Cotton-Seed Hulling, Reducing, and Separating Machines; and I declare the following to be a full, clear, and exact description of the same, such as will enableothers skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification. i

The invention relates to hullingand reducing mechanism for cotton-seed and other purposes; and it. consists in the'novel'construction and combinations of parts, as hereinafter set forth.

In the accompanying drawings, Figure 1 represents a side view of the machine. Fig. 2 is an end view. Fig. 3 is a transverse vertical section. Fig. 4 is a longitudinal section. Figs. 5 and 6 represent details of the construction. Fig. 7 is a detail View of the annulus m. Fig. 8 is a detail fragmentary view! showing the space separating the washer and brace Y and shaft H.

. form shoulders (I just inside the edges of the cover-casing. Slides E, resting on their shoul ders,serve to receive extraneous articles when thrown oif by the flail-beaters F. Such arti-' cles can be removed at any time during the operation of the machine by drawing out the shoulder-slide on which it rests.

G indicates the hopper attached to the cover-casing, and H the opening in said covercasing, through which the seed is drawn into the chamber of the machine.

The screen-casing may be se-' The perforations of the screen-casing vhich' forms the lower part or bottom of the cham her, are of proper size to allow the hulled seed to pass through. If further reducing is desired, the perforations may be-made smaller,

or this screen-delivery may be made into a second beater-chamber below the first, wherein the hulled seed may befurther reduced.

H indicates the shaft, seated in suitable bearings K and provided with a pulley or I other means for applying 'power. To this shaft are screwed or otherwise secured the perforatedpins or supports L L, which are arranged parallel to each other, being separated by a sufficient distance for the introduction of the flail-beaters F, which are pivoted on the bolts m, which extend transversely .through the perforations of the supports L.

These perforations are made near the ends'of the supports, it being preferred usually to have an interval between the shaft and the beaters to avoid obstructive action of the material near the shaft, and thus increase Each transthe defective swing of the fiails. verse bolt or rod m is designed to carry a series of beaters, which consist of elongated metallic plates, each having atits inner end aneye or bearing n, which. engages the bolt or rod m preferably in such a manner that it v Between 4 the eyes of the beaters or flails are placed can have pivotal motion thereon.

washers w, and washers should also be placed between the eyes of the beaters or flails and the check-pieces.

In the operation of the machine it is de-' signed usually to rotate the shaft carrying the flails or beaters about sixteen hundred times a minute; but the speed of rotation may be varied in accordance with the nature of the work to be accomplished. The efficiency of the flails or beaters is materially increased by means of the rasp ends orplates. P, which are made of steel after the manner of wood-rasps, the steel being, however, usually soft enough for boring, sothat the raspplate can be attached to'the beater-plate by means of rivets. These rasp-plates act upon the cotton-seed to remove the hull portion with great facility and are of further advan- Y tage in weighting the outer ends of the beat ers, thereby increasing their centrifugal force. The machine is designed to be very efficient in reducing the hulls and kernels of cottonseed, the product being beaten and blown throughthe perforations on the bottom screencasing. These perforations are usually made from one-quarter to nine thirty-seconds of an inch in diameter when it is designed to have the kernels pass through, in entire or almost entire form, but without the hull portions. The screen-casing is usually made on a radius of thirteen inches, the ends of the flails or heaters passing about one-half inch from the inner surface of the screen.

The capacity of the machine can be increased by adding to its width and using a greater number of flails.

Sometimes a second beating-chamber may be made below the main chamber, the screen of the latter delivering the material into the lower chamber cleaned of extraneous matter and for the main part hulled, the finishing being accomplished by the beater in the lower chamber. In this double construction it is preferred to increase the diameter of the perforations of the screen of the first or main reducing-chamber to three-eighths of an inch for cottonseed.

In order to prevent outward bowing of the rods on through centrifugal action, a perforated annulus m is provided midway thereof, through which pass the said rods, said annulus also acting as a washer for the arms F.

An annular combined washer for the beaterblades and brace for the pivot-rods thereof is provided centrally of the length of said rods, said washer being perforated for the passage of said rods. (See Fig. 7.)

It will be noted that the radial separated pins or supports L and the annular combined washer and brace Y, which has a space y separating its inner peripheral surface from shaft H, in connection with inlet-opening H, which is in the end wall of the chamber, act to allow a free and unobstructed flow of the seed into the chamber.

Having described this invention, what I claim, and desire to secure by Letters Patent, is-

1. In a machine of the character described, the combination of the chamber having the rotarybeaters, the screen-bottom, an upper portion of greater width than said bottom, and longitudinal removable ledges between said upper portion and bottom, substantially as specified.

2. In a machine of the character described,

the combination with the chamber having an inlet-opening in its end wall, the rotary shaft in said chamber, the separated radial pins or supports upon said shaft, the pivot-rods engaging said pins or supports, the pivotal beaters upon said rods, and an annular combined washer and brace having perforations therein for the passage of said rods, and having its inner peripheral surface separated from said shaft, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

CORNELIUS YOUNG.
